Hi Michael - Very nice addition to your Mdina collection! A large Rosenthal cylinder vase and fairly hard to find.

These I think are all fairly early and were introduced around 1971 I think, they were also produced after Michael left i believe, although not for that long. This design looks great in the light, personally i think its one of the nicest designs that they produced, certainly a favourite of mine. Congratulations on a super find!

That's the beauty of glass and colour - it does things quite differently to paint.

When you see blue glass, the chemical make up of the glass is such that blue light is reflected back to you from it - it absorbs all the other colours.

When you see yellow glass, it is yellow being reflected back at you, all the other colours are absorbed.

When you look through glass which is a layer of blue over a layer of yellow, all that gets through is the red/purple end of the spectrum - because both blue and yellow wavelenghts are being reflected off the other side, only reddy purple gets through it.

The very best sort of ear-pull!A lovely egg-shape with the sculptural effect of the pulls enhancing rather than detracting overall, completed perfectly with the small and neat button rim; the very dark amethyst background really shows the iridesence and other silver chloride effects up - and the whole shape sends the silver effects off at differing angles, swirling and sweeping over it. It's elegant - not a word which can often be applied to early Studio glass. The button rim would suggest pre-'Boffo; the whole thing says; "Michael Harris made me," to me. Everything about it is just "right", isn't it?

I've just got hold of mine to compare - and to try to see if I can see through it.I've got more iridesence (tons and tons ) - but the positioning of the lugs on yours is so much better than mine, the profile is a far, far more pleasing sculpture and a much stronger artistic statement.

I've held it up to the light and peered trhough the rim. I can see shades of amethyst and purple (yes, proper deep purple, but this must be something to do with colours overlapping and the physics of transmission and refraction rather than a deep purple glass.The clear casing on mine is very thick - and it has that diffuse electric blue cloudy effect through it.
